What are risks of high blood sugar during pregnancy?

Controlling blood sugar is hard, especially during pregnancy, but it is important to work at it. When blood sugar is high most of the time in a woman with diabetes, she might have certain health problems.

A woman with gestational diabetes whose blood sugar stays high has an increased chance of:

  • Preeclampsia (high blood pressure, protein in urine, increased swelling)
  • Preterm birth (baby born before 37 weeks)
  • C-section

In a woman with preexisting diabetes (which includes type 1 and type 2), blood sugar that remains high can trigger or worsen certain health problems, including:

  • High blood pressure
  • Preeclampsia
  • Kidney disease
  • Nerve damage
  • Heart disease
  • Blindness

Also, a woman with preexisting diabetes whose blood sugar remains high has an increased chance of:

  • Miscarriage
  • Preterm birth
  • Stillbirth
  • C-section
